Effective roughness modelling as a tool for soil moisture retrieval from C-and L-band SAR
(Copernicus Publications, 2011)
Artículo / Artikulua,
Soil moisture retrieval from Synthetic Aperture Radar (SAR) using state-of-the-art backscatter models is not fully operational at present, mainly due to difficulties involved in the parameterisation of soil surface ...
Error in radar-derived soil moisture due to roughness parameterization: an analysis based on synthetical surface profiles
(MDPI, 2009)
Artículo / Artikulua,
In the past decades, many studies on soil moisture retrieval from SAR demonstrated a poor correlation between the top layer soil moisture content and observed backscatter coefficients, which mainly has been attributed ...
On the soil roughness parameterization problem in soil moisture retrieval of bare surfaces from synthetic aperture radar
(MDPI, 2008)
Artículo / Artikulua,
Synthetic Aperture Radar has shown its large potential for retrieving soil moisture maps at regional scales. However, since the backscattered signal is determined by several surface characteristics, the retrieval of soil ...
Influence of surface roughness spatial variability and temporal dynamics on the retrieval of soil moisture from SAR observations
(MDPI, 2009)
Artículo / Artikulua,
Radar-based surface soil moisture retrieval has been subject of intense research during the last decades. However, several difficulties hamper the operational estimation of soil moisture based on currently available ...
On the assimilation set-up of ASCAT soil moisture data for improving streamflow catchment simulation
(Elsevier, 2018)
Artículo / Artikulua,
Assimilation of remotely sensed surface soil moisture (SSM) data into hydrological catchment models has been identified as a means to improve stream flow simulations, but reported results vary markedly depending on the ...
Factors controlling sediment export in a small agricultural watershed in Navarre (Spain)
(Elsevier, 2012)
Artículo / Artikulua,
It is recognised that the hydrological and erosion processes in watersheds are very much conditioned by
the (inter)action of a number of variables. This paper covers a 15-year period of studying those factors
that have ...
Clasificación de cultivos en la zona media de Navarra mediante imágenes radar polarimétricas
(Universidad Politécnica de Valencia, 2010)
Artículo / Artikulua,
Navarra lleva años empleando la técnica de clasificación
supervisada de imágenes multiespectrales
de satélite para la realización de la estadística
agraria. La cubierta nubosa, muy
habitual en esta zona, limita e incluso ...
Evaluation of TOPLATS on three Mediterranean catchments
(Elsevier, 2016)
Artículo / Artikulua,
Physically based hydrological models are complex tools that provide a complete description of the different processes occurring on a catchment. The TOPMODEL-based Land-Atmosphere Transfer Scheme (TOPLATS) simulates water ...
Automatic detection of uprooted orchards based on orthophoto texture analysis
(MDPI, 2017)
Artículo / Artikulua,
Permanent crops, such as olive groves, vineyards and fruit trees, are important in European agriculture because of their spatial and economic relevance. Agricultural geographical databases (AGDBs) are commonly used by ...
Evaluation of 2D models for the prediction of surface depression storage using realistic reference values
(Wiley, 2016)
Artículo / Artikulua,
Depression storage (DS) is the maximum storage of precipitation and runoff in the soil surface at a given slope. The DS is determined by soil roughness that in agricultural soils is largely affected by tillage. The direct ...
